-# Callback & Dual Scheduling Analysis
-
-**Document Created**: 2025-08-26 11:17:26 UTC  
-**Author**: Matthew Raymer  
-**Status**: 🔄 **RESEARCH & ANALYSIS**

-## 🎯 **REQUIREMENTS ANALYSIS**
-
-### **User Feedback Summary**
-> "BTW, I still think it's worth starting a branch where we use the notification plugin, but a note on the plugin itself: seems like it'll need a couple things. One is to accept some callbacks (eg. for API calls out to a reporting service and then saving in the DB). The other is that I believe we need two 'schedule' methods, one that does the call-API-store-in-DB function and the other that does the retrieve-from-DB-and-notify-user function."
-
-### **Core Requirements Identified**
-1. **Callback System**: Accept callbacks for external service integration
-2. **Dual Scheduling**: Separate content fetch from user notification
-3. **API Integration**: Support for external reporting services
-4. **Database Operations**: Callback-based storage and retrieval
-
----
-
-## 🔍 **CURRENT IMPLEMENTATION ANALYSIS**
-
-### **Existing Scheduling Method**
-```typescript
-// Current single method approach
-async scheduleDailyNotification(options: NotificationOptions): Promise<void>
-```
-
-**Current Behavior**:
-- Single method handles both content fetching and notification scheduling
-- Limited to basic URL fetching without callback support
-- No separation of concerns between data operations and user notification
-- Basic error handling without external service integration
-
-### **Current API Call Handling**
-```typescript
-// Basic URL fetching in Android implementation
-String url = call.getString("url", "");
-// No callback support for API responses
-// No database storage integration
-// No external service reporting
-```
-
-### **Gap Analysis**
-- ❌ **No callback mechanism** for external service integration
-- ❌ **No dual scheduling** - single method handles everything
-- ❌ **Limited API integration** - basic HTTP requests only
-- ❌ **No database callback support** for storage operations
-- ❌ **No reporting service integration** for analytics
-
----
-
-## 🏗️ **PROPOSED ARCHITECTURE**
-
-### **Dual Scheduling Methods**
-
-#### **Method 1: Content Fetch & Storage**
-```typescript
-async scheduleContentFetch(options: ContentFetchOptions): Promise<void>
-```
-
-**Purpose**: Handle API calls and database storage
-**Responsibilities**:
-- Make API calls to external services
-- Execute database storage callbacks
-- Handle retry logic and fallbacks
-- Report to analytics/reporting services
-- Cache content for later use
-
-#### **Method 2: User Notification**
-```typescript
-async scheduleUserNotification(options: UserNotificationOptions): Promise<void>
-```
-
-**Purpose**: Retrieve stored content and notify users
-**Responsibilities**:
-- Retrieve content from database/cache
-- Execute user notification callbacks
-- Handle notification display logic
-- Manage user interaction callbacks
-- Track notification engagement
-
-### **Callback System Architecture**
-
-#### **Callback Types**
-```typescript
-interface CallbackSystem {
-  // API callbacks
-  apiCallbacks: {
-    onSuccess: (response: any) => Promise<void>;
-    onError: (error: Error) => Promise<void>;
-    onRetry: (attempt: number) => Promise<boolean>;
-  };
-  
-  // Database callbacks
-  databaseCallbacks: {
-    onStore: (data: any) => Promise<void>;
-    onRetrieve: (id: string) => Promise<any>;
-    onError: (error: Error) => Promise<void>;
-  };
-  
-  // Reporting callbacks
-  reportingCallbacks: {
-    onMetrics: (metrics: NotificationMetrics) => Promise<void>;
-    onAnalytics: (event: string, data: any) => Promise<void>;
-  };
-}
-```
-
-#### **Callback Registration**
-```typescript
-interface CallbackRegistry {
-  registerCallback(type: CallbackType, callback: Function): void;
-  unregisterCallback(type: CallbackType, id: string): void;
-  executeCallback(type: CallbackType, data: any): Promise<void>;
-  validateCallback(callback: Function): boolean;
-}
-```
-
----
-

-   
-   interface UserNotificationOptions {
-     contentId: string;
-     notificationCallbacks: NotificationCallbacks;

-
-```typescript
-// Asynchronous callback execution with error handling
-async executeCallback(type: CallbackType, data: any): Promise<void> {
-  try {
-    const callbacks = this.getCallbacks(type);
-    const promises = callbacks.map(callback => 
-      this.executeSingleCallback(callback, data)
-    );
-    
-    await Promise.allSettled(promises);
-  } catch (error) {
-    this.handleCallbackError(type, error);
-  }
-}
-```
-
-### **Error Handling Strategy**
-
-```typescript
-// Comprehensive error handling for callbacks
-private handleCallbackError(type: CallbackType, error: Error): void {
-  // Log error for debugging
-  this.logger.error(`Callback execution failed for type: ${type}`, error);
-  
-  // Execute error callbacks if available
-  this.executeErrorCallbacks(type, error);
-  
-  // Fallback to default error handling
-  this.executeDefaultErrorHandling(type, error);
-}
-```
-
-### **Retry and Fallback Logic**
-
-```typescript
-// Retry logic with exponential backoff
-async executeWithRetry<T>(
-  operation: () => Promise<T>,
-  maxRetries: number = 3,
-  baseDelay: number = 1000
-): Promise<T> {
-  for (let attempt = 1; attempt <= maxRetries; attempt++) {
-    try {
-      return await operation();
-    } catch (error) {
-      if (attempt === maxRetries) throw error;
-      
-      const delay = baseDelay * Math.pow(2, attempt - 1);
-      await this.sleep(delay);
-    }
-  }
-  throw new Error('Max retries exceeded');
-}

-# Daily Notification Plugin - Development TODO
-
-**Last Updated**: 2025-08-26 11:17:26 UTC  
-**Current Branch**: research/notification-plugin-enhancement  
-**Status**: 🔄 **RESEARCH & ANALYSIS PHASE**
-
-## 🎯 **NEW REQUIREMENTS ANALYSIS**
-
-### **Callback & API Integration Requirements**
-
-Based on user feedback analysis, the plugin needs enhanced callback mechanisms and dual scheduling methods:
-
-1. **API Callback Integration** - Accept callbacks for external API calls and database storage
-2. **Dual Scheduling Methods** - Separate methods for content fetching vs. user notification
-3. **Reporting Service Integration** - Support for external reporting and analytics services
-
-### **Current Implementation Gap Analysis**
-
-- ✅ **Basic scheduling**: Single `scheduleDailyNotification` method exists
-- ❌ **Callback system**: No callback mechanism for external services
-- ❌ **Dual scheduling**: No separation between content fetch and user notification
-- ❌ **API integration**: Limited to basic URL fetching without callback support
-- ❌ **Database storage**: No callback support for external database operations
